Silver, copper and chromium can be obtained by electrolysis of their aqueous solutions. but 1 St A group and 2 ND A group elements are more reactive so they can be obtained by electrolysis of their molten solution.

Which one of the following metals could not be obtained on electrolysi...
Explanation:
Metals can be obtained from their salts by the process of electrolysis. However, not all metals can be obtained by this method.
B) Magnesium (Mg) cannot be obtained on electrolysis of its aqueous salt solution because it is highly reactive and has a strong tendency to form compounds with water. Hence, it is not stable in aqueous solutions and decomposes to form magnesium oxide and hydrogen gas before it can be deposited on the cathode.
A) Silver (Ag) can be obtained on electrolysis of its aqueous salt solution as it is less reactive than magnesium and stable in aqueous solutions.
C) Copper (Cu) can be obtained on electrolysis of its aqueous salt solution as it is less reactive than magnesium and stable in aqueous solutions.
D) Chromium (Cr) can be obtained on electrolysis of its aqueous salt solution as it is less reactive than magnesium and stable in aqueous solutions.
In summary, magnesium cannot be obtained on electrolysis of its aqueous salt solution due to its high reactivity and tendency to form compounds with water.
